Ground level aimed panel is subject to shading from the RV itself so you need lots of wire depending on how long the rig is and where the wires go to. Slide outs and awnings make shade too.
If that means the panel has to go in your neighbour's spot, you will have to instead, move the panel during the day from one side of the rig or from one end of the rig to the other to keep it in your own "yard" and clear of the rig's shadow as that changes location.
Ah, secret pains of portables that owners don't want to talk about :) ...
Add more panels to the roof!
In the warm half of the year, the sun goes around more than 180 degrees. So if you place the panel out to the sunny side, it has to be far enough out to "see" around the back and front ends somewhat.
Tilted panel won't see much with the sun a few degrees behind. He'll have to rotate it at least twice a day.
Contraptions with tilted panel on the roof is not something to enjoy, either. You climb up and down few dozen times, and then it's not fun anymore. Tilted and portable on the roof would be the worst of both worlds - you'll have to climb to tilt and/or rotate it, and also to bring the whole cabooze up and down.
